Arid-region corn sowing machine

Abstract

The invention provides an arid-region corn sowing machine and relates to agricultural corn sowing machines. The arid-region corn sowing machine comprises a vehicle body, a sowing device is arranged atthe front part of the vehicle body, wherein the sowing device comprises a seed metering device and a tire; the seed metering device and the tire are coaxially arranged on a transmission shaft; the transmission shaft is provided with a plurality of earth covering wheels; a plurality of seeders are uniformly arranged on the earth covering wheels; each seeder comprises a soil drill, a soil transportation device, a soil placement device and a seed placement device; seed boxes are further arranged on the earth covering wheels; the seed placement devices are connected with the seed boxes; a water tank is further arranged on the vehicle body; the water tank is provided with a water outlet pipe; the water outlet pipe is arranged behind the seed metering device; the water outlet pipe is further internally provided with a proportional valve. Compared with the prior art, the arid-region corn sowing machine can be used for easily digging ditches on a hard land and putting corn seeds into the ditches; the water feeding amount is calculated according to the soil moisture and water is automatically supplemented; the seeds are automatically covered with dug-out soil again and the soil is compacted through a compacting wheel so as to prevent the soil moisture from losing.

Description

technical field [0001] The invention relates to an agricultural corn seeder, in particular to an arid area corn seeder. Background technique [0002] The semi-arid area in the west of Heilongjiang Province is located in the Songnen Plain in the southwest of the province. It is one of the main grain producing areas in our province, including Longjiang, Gannan, Fuyu, Tailai, Dumont, Qiqihar, Lindian, Anda, Daqing, Zhao Dong, Zhaozhou, Zhaoyuan 12 counties (cities). The soil types are carbonate meadow chernozem, carbonate meadow soil, salinized or alkalized meadow soil, meadow alkali (salt) soil and aeolian sandy soil. It belongs to the mid-temperate zone and semi-arid continental monsoon climate. It is the region with the highest heat and relatively little rainfall in the whole province. The average annual precipitation is 250-500 mm, and more than 80% of it is concentrated in summer, and winter and spring are less than the annual precipitation. 15% of. It is known as "nine...

Problems solved by technology

Corn planting in spring has become a difficult problem. The existing corn planters have not been considered to be poor in business conditions, soil compaction in poorly prepared land and many other thorny problems that are not conducive to sowing and germination. Reduce the labor intensity of farmers, increase the germination rate of seeds, and improve the efficiency of sowing
